For .ca domains, the length of the pending delete period depends upon when it exits the redemption period, which will vary between domains.
After a .ca domain exits the redemption period, it is listed on a TBR (To Be Released) list with CIRA (the .ca registry). After being in TBR for at least 60 hours, it will participate in the next scheduled TBR session, which is held by CIRA every Wednesday. During the TBR session, the domain can be registered by anyone who has backordered it. If it's not registered, the domain is released within 24 hours to the general public for anyone to register.
